High Current Isolated Gate Driver for IGBTs

This project design consists of galvanically isolated single channel gate driver IC and dedicated isolated DC-DC gate drive power supply with bipolar output +15V/-9V. This compact module can control IGBTs in inverters. The isolated high current IGBT gate driver module is a simple solution for power drivers, consisting of a gate driver chip 1ED3124MC12H and an isolated 2W DC-DC converter (R12P21509D). This module is optimized for high-frequency operations and can provide high gate driver currents up to 14A, making it suitable for applications such as half-bridge, full-bridge, and single IGBT.

Logic input: for the output switching behavior there are two possible input modes to control the IGBT. At non-inverting mode IN+ controls the driver output while IN- is set to low. At inverting mode IN- controls the driver output while IN+ is set to high. A minimum input pulse width is defined to filter occasional glitches.
